Bigger throttle body

[alf74]

Honda fit should have a 50mm electronic throttle body (with drive by wire system).
Usually a 1.5 engine can use a 60/62 mm throttle body...
Is there anyone who already use a bigger throttle body or knows where to buy it?

Another remark:

Spoon throttle body (non electronic), instead, has a diameter of 58mm.
What makes me think is:
- Honda Jazz/Fit European: plastic intake manifold + 56mm (original) throttle body
- Honda Fit American: aluminium intake manifold + 50mm (drive by wire) throttle body

Don't you think there's something we could upgrade?!!

Do you know if i can put this and in my 1.3?

[alf74]

You can, if you don't have a drive by wire throttle control, of course...

We can still take our manifolds off, port and polish them! And port match the throttle body! (a bit)

You can bore it. I have done it in my City. Check this guy


www.maxbore.com just $100

Yes, but boring our throttle body you'll gain no more than 3 mm for $100 (and the throttle body becomes very thin...). I don't know if it's worth boring it or buying a bigger one.

I have done mine and the gain is good
